Explain the breathing process in the following living organisms : A) Frog, B) Earth worm, C) cockroach, D) Fish
Answers
Answer:
frog from its lungs
Fish by its gills
Earthworm by its skin
cockroach by its external valves called trachea.
A frog may also breathe much like a human, by taking air in through their nostrils and down into their lungs. ... To elimate the carbon dioxide in the lungs the floor of the mouth moves down, drawing the air out of the lungs and into the mouth.
They breathe through their skin. Air dissolves on the mucus of their skin, so they MUST stay moist to breathe. If worms dry out, they suffocate. As fresh air is taken in through the skin, oxygen is drawn into the worm's circulatory system, and the worm's hearts pump the oxygenated blood to the head area.
In cockroach, respiration occurs through spiracles – a small opening on the sides of its body. When air through external openings, enters into its respiratory system, spiracles serve as muscular valves paving way to the internal respiratory system.
A fish breathes by taking water into its mouth and forcing it out through the gill passages. As water passes over the thin walls of the gills, dissolved oxygen moves into the blood and travels to the fish's cells.
